CLAMP FOR LUMBER AND THE LIKE.

Specification of Letters Patent. Patented Sept. 12, 1911.

Application filed February 21, 1911.

Serial No. 610,012.

To all whom it may concern:

Be it known that I, JOHN P. HINRIoHs, a citizen of the United States ofAmerica, and resident of Napa, in the county of Napa and State ofCalifornia, have invented certain new and useful Improvements in Clampsfor Lumber and the Like, of which the fol lowing is a specification.

This invention relates to clamps for lumber, the same being for useprimarily on lumber wagons for the purpose of binding the load thereon,although it can be used to advantage on railway rolling stock, such asopen cars on which lumber is piled.

An object of this invention is to protect the lumber against injuriousaction of a cable or binding element in order to prevent the saidbinding element cutting into the lumber at the corners or sides, yetpermitting the said binding element to be drawn taut for the purpose ofeffectually holding the load on the conveyance.

A further object of this invention is to provide a guard havingrenewable wearing parts, which renewable wearing part acts as a guidefor the binding element in order that displacement of the bindingelement with relation to the protecting element may be obviated.

With the foregoing and other objects in view, the invention consists inthe details of construction and in the arrangement and combination ofparts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to theaccompanying drawings forming part of this specification wherein likecharacters denote corresponding parts in the several views, and inwhich- Figure 1 illustrates a view in perspective of a fragment of aload of lumber showing the application of the invention thereto; Fig. 2illustrates a perspective view of one of the protecting members.

In these drawings 4; denotes a pile of lumber and 5, 5, denote theguards which guards are duplicates of each other. Each guard comprisespreferably a metallic plate of angular formation in order that the saidplates will fit the top corners of a load as shown in Fig. 1. Each platehas one of its corners terminating in a lug 6 having an aperture 7 forthe reception of a flexible connection 8 which flexible connection ispreferably slightly longer than the width of the pile of lumber ormaterial to which the guards are to be applied. One purpose of theflexible connection 8 is to prevent separation of the vprotectingmembers so that they can be carried conveniently and kept together forconvenience of use. The purpose of the upturned lug 6 is to providemeans for attaching the flexible connection to the plate in order thatthe said flexible connection may be used without marring the lumber ormaterial to which the plates are applied for by this arrangement, theflexible connection is not pressed against the lumber or the material.

The plate is further provided with a combined guide and wear strip 9which may be secured to the plate in any appropriate manner, here shownas being attached by screws 10 passing through the strip and havingtheir ends embedded in the said plate. The strip is of curved formationtransversely forming a trough-like way in which the binding element 11is guided and as there is considerable friction and wear between thebinding element'll and the wear strip 9, the utility of the said wearstrip will, it is thought, be apparent. Should the wear strip 9 becomeimpaired through the action of the binding member thereon, the said wearstrip can be renewed. While I have shown a cable as the binding element,it is well known that chains are frequently used for the purpose ofholding a pile of lumber on a conveyance so that the utility of the wearstrip will be more fully recognized when it is considered that it may beused in connection with chains since the action of chains on the wearstrip will be more damaging than an ordinary cable. It is on account ofthis consideration that the importance of the wear strip, as a part ofthe protecting plate or as combined therewith, becomes apparent.

I claim In a clamp for lumber or the like comprising right angledplates, a detachable Wearing strip comprising a substantially a lug, andmeans for connecting the said long right angled member semi-circular inplates. 10 cross section, provided on each of the said In testimonywhereof, I hereunto afiix my plates, said Wearing strip being providedsignature in the presence of two Witnesses.

With apertures to receive a means for fas- JOHN P. HINRICHS. tening aWearing strip to each of the 'right Witnesses:

angled plates, one corner of each of the CHAS. E. TROWER,

plates being apertured and shaped to form B. I. CHAPMAN.

Copies of this patent may be obtained for five cents each, by addressingthe Commissioner of Patents,
